The Lowdown
G’day, Rusty here.
Alright, we’ve got a proper run of swell coming in for Lakey Pipe. This isn’t a quick flash in the pan; we’re looking at a solid, consistent window of surf that’s going to stretch for over a fortnight. The pattern is driven by a persistent, long-period SSW groundswell, and the wind is staying mostly cross-offshore, keeping the reef clean. The water temp is sitting about average for this time of year.
The standout period kicks off on Tuesday, August 11th, but there’s a catch. Tuesday morning and afternoon are pumping out a solid 10ft swell with a very long period of 17 seconds, and the wave energy is enormous at 4394 and 5839 (moderate to very strong). That’s a lot of power. For the experienced crew, the shapes will be there, but for most, it’s going to be too big and too powerful to handle, especially on a steep reef like this. It’s a day to sit on the cliff and watch.
The real sweet spot, and the absolute pick of the entire outlook, is from Wednesday, August 12th, right through Monday, August 17th. For seven straight days, Lakey Pipe is serving up clean, excellent surf for experienced surfers. Expect swell heights between 5ft and 7ft, with periods of 14 to 17 seconds, delivering solid wave energy (1044 to 2395, moderate to strong). The wind is a gentle to light breeze from the SE/SSE, making for clean, cross-off conditions. This is the window for a proper session with plenty of power but with control. The crowds say “often,” so expect some locals and travellers out, but the consistency is high, so waves will be on offer.
We see a slight dip in energy on August 18th and 19th, with a bit more wind (12 mph), and the swell starts to ramp up again into the “too big for this break” territory. August 21st to 22nd brings another solid pulse of 10ft swell from the SW with periods up to 18 seconds, and the wave energy is back up over 4500 (very strong). This is another big-wave set that only the gnarliest should consider.
The run starts to ease off from Sunday, August 23rd, and we finish the outlook on Wednesday, August 26th with a smaller, cleaner 5ft swell and a period of 14 seconds, offering very good conditions but with weaker energy (976, moderate).
So, overall: the first two days are for the elite. The clear winner is the spell from Wednesday the 12th to Monday the 17th. That’s your window for the best mix of clean conditions, size, and power.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
